1 LushOne Inca Synth Module Build Instructions

2 Getting started If you can build the LushOne base module then then building the Inca should be easy Remember: Accuracy and neatness is more important than speed Get it working first time These instructions will guide you but I assume you are familiar with basic techniques and equipment All components except the power-in are mounted on the circuit board no slow, fiddly point to point wiring! 2 LushOne Inca synth module build instructions

3 Build order Build in any order you like, but I suggest: Patch sockets LEDs ICs Resistors, capacitors Transistor, diodes External connectors Power leads Variable resistors Joystick 3 LushOne Inca synth module build instructions

4 Front The following components are mounted from the front: Patch sockets Variable resistors (but not trimmers) Breakout connector LEDs 4 LushOne Inca synth module build instructions

5 Back The following components are mounted from the back: Everything not on the front! 5 LushOne Inca synth module build instructions

6 Patch sockets 19 small silver patch sockets fit from front of board Fit in the large, labelled circles Not the four mounting holes in the extreme corners Solder round rim on back Suggest you fit first so you can make them sit nicely flush with the board 6 LushOne Inca synth module build instructions

7 LEDs Both LEDs are mounted from the front Short-lead goes towards the square pad Depending on your case design you might want to lift the LEDs up above the board 7 LushOne Inca synth module build instructions

8 ICs Designation Type Comment U201,U203,U401 TL Pin U or equivalent 8 Pin U202 78L05 3 Pin transistor-style case All ICs are mounted from the back ICs are provided unsocketed You can add sockets if you like! Positions and orientations are marked on the silk-screen Pin 1 also has a square pad The voltage regulator has the same case as the transistors check the labels! Orientation is shown on silk-screen 8 LushOne Inca synth module build instructions

9 Resistors All resistors are mounted from the back Resistor R208 R306 R416,R415,R413,R217 Value 220R 470R 1k Resistors are all mounted vertically Labels are not in a set position relative to the symbol look for the closest label The round silk-screen symbol shown above shows the resistor locations R k R411,R k R k R311,R408,R414,R211,R205,R207, R417 R309 R312,R401,R404 10k 22k 27k Value Colours 220R Red, Red, Brown, Gold 470R Yellow, Purple, Brown, Gold 1k Brown, Black, Red, Gold 2.2k Red, Red, Red, Gold 4.7k Yellow, Purple, Red, Gold 8.2k Grey, Red, Red, Gold 10k Brown, Black, Orange, Gold R405 47k 22k Red, Red, Orange, Gold R402,R403 R307,R305,R302,R301,R310,R409, R410,R412,R209,R313,R418 68k 100k 27k 47k 68k Red, Purple, Orange, Gold Yellow, Purple, Orange, Gold Blue, Grey, Orange, Gold R304,R k 100k Brown, Black, Yellow, Gold R202,R203 R212,R k 1M 330k 470k 1M Orange, Orange, Yellow, Gold Yellow, Purple, Yellow, Gold Brown, Black, Green, Gold 9 LushOne Inca synth module build instructions

10 Capacitors Designator Value Type C402 10n Ceramic C401 C201, C202, C204, C205, C208, C211, C302, C303, C403, C404, C405 10n 100n Polyester Box Ceramic All capacitors are mounted from the back Capacitors are marked with one of the symbols shown above For electrolytic capacitors the + lead (longer lead) is labelled and indicated by the square pad. Some capacitors may come with either wide or narrow leg spacing. Connect as shown below. Connect narrow legs to these pads C203 1u Ceramic C210,C212, C301,C406 10u Electrolytic Connect wide legs to these pads Value Marking C206,C209 47u Electrolytic C401 Polyester Box 10n n 104 1u 105 or 1u 10 LushOne Inca synth module build instructions

11 Transistors, diodes Q201, 2N3904 Q301 NPN Q401 J112, 2N5457 or similar N Channel FET D201, D202, D203, D401, D402, D403, D404, D405 1N4148 All Transistors and diodes are mounted from the back. Transistors are marked showing the package orientation. Check you have the transistors and not the voltage regulator! There are both NPN and FET transistors check you have the right one Q201 is a noise source and only two leads are connected (left and centre as shown in the photo above) The third lead may be cut off near the body and not connected to avoid risk of picking up electrical interference Diodes are all vertically mounted and shown with the square symbol. The diode s stripe should be towards the printed square / square pad Small line coming out of square on silk screen shows direction of the lead. 11 LushOne Inca synth module build instructions

12 Connector A passive 3.5mm mono socket is provided for signal break-in/break-out Connect from the top of the board to footprint P307 Smallest tag goes in the smallest hole for orientation 12 LushOne Inca synth module build instructions

13 Power leads The LushOne Inca can be connected to the LushOne base module for power Connect three leads to the LushOne Power In connectors Suggest: Red = +9V Black = 0V Blue = -9V Connect other end of power leads to the spare terminals next to the Power In on the LushOne base If you have more than two modules in your system see next slide 13 LushOne Inca synth module build instructions

14 Power with more than two LushOne modules To connect more than one LushOne module to a LushOne base it is desirable to use a star power connection point A simple terminal block is an easy choice Connect as shown in the diagram Switched output of LushOne base goes to star point Each additional module connects to the star point for its power 9V 9V eg LushOne Contour LushOne Base +9V 0V -9V Distribution star point eg LushOne Inca 14 LushOne Inca synth module build instructions

15 Variable resistors RV201 RV301, RV302, RV303, RV304, RV305, RV401 10k Seven variable resistors are mounted where shown on front of board You may need to bend the pins slightly to make them sit properly 15 LushOne Inca synth module build instructions

16 Joystick Insert the joystick where indicated on the front The hat for the joystick is a push-fit 16 LushOne Inca synth module build instructions

17 Checking time Congratulations building should now be complete! Take a break Time to check: No parts left-over All parts (particularly ICs) in the right way No bad solder joints or unsoldered joints Power connectors on correctly (very important!) No solder bridges or other problems Good luck 17 LushOne Inca synth module build instructions
